He is such a good athlete you could make the argument he could "learn" lots of positions, but fergodsakes, he ran for 4500 yards. You don't do that running only "in space" like some people have said. He has proven he can run inside, outside , break tackles or break ankles, he has shown he can do it all running the football. As for his size, he is already bigger than 2 of Mel Kiper's top 5 RB prospects. Why aren't they being slotted for WR? I also think he may not have had a focus on gaining weight for the QB position, I think he could easily add 10-15 punds of good weight if gaining weight was a focus for him. As far as blocking, it is nice if he can learn to do it, but Barry Sanders and Chris Johnson didn't really seem to do much of it and they both are single season. 2000 yard rushers. He has no experience at WR, why have him start from scratch learning a role vs playing a posoiton he would be able to learn much faster and has already shown good performance at?
